A Newark school teacher charged with having sex with one of her 14-year-old students multiple times in Jersey City made her first court appearance on the charges yesterday.

Elyse Cromwell, 27, of Bergen Avenue in Jersey City, is charged with aggravated sexual assault on the boy, as well as endangering the welfare of a child and child abuse.

Cromwell allegedly had sex with the boy on multiple occasions “while acting in the position of said victim’s homeroom and English teacher,” the complaint says. The complaint says she “performed prohibited sexual acts upon” the boy, who is now 15 years old.

Cromwell, who was arrested yesterday, appeared yesterday afternoon in Central Judicial Processing court in Jersey City via video link from Hudson County jail in Kearny. She wore the green garb of the jail and her brown hair was in a long braid.

Hudson County Superior Court Judge Francis Schultz had already set Cromwell’s bail at $300,000 cash or bond, but CJP Judge Margaret Marley ordered that as a condition of bail Cromwell must have no contact with anyone under 18.

The complaint says Cromwell is employed by the Newark Board of Education as a high school teacher. Newark school officials did not immediately return a call seeking further information.
